I am using the latest 201605 API.
While it is fine getting Search Network data (AdNetworkType2 = SEARCH) from Account Performance Report; for Display Network (AdNetworkType2 = CONTENT), it always returns an empty report. (or all zeros when includeZeroImpressions is set to TRUE)
I tried both AdNetworkType1 and AdNetworkType2 fields but it was no help. Also tried Campaign Performance Report with AdvertisingChannelType = DISPLAY, again, I am getting empty reports (there's data when AdvertisingChannelType = SEARCH).
I have already checked via account management that data is indeed available for Google Display Network (not zeros).
AWQL being used is as follow:
SELECT Clicks, Impressions, Ctr, AverageCpc, AverageCpm, Cost, ClickConversionRate, CostPerConvertedClick, InvalidClicks, InvalidClickRate, ConvertedClicks, Date
FROM ACCOUNT_PERFORMANCE_REPORT
WHERE AdNetworkType2 = CONTENT
